[First Embodiment]
First, the information processing system according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of the information processing system according to the first embodiment.

The information processing system 60 is a system for transmitting/receiving and managing mail. The information processing system 60 includes the information processing device 10 and terminals 20 and 30. Each device included in the information processing system 60 can communicate information via the network 50. The network 50 may be a wired network or a wireless network. The numbers of the information processing devices 10 and the terminals 20, 30 included in the information processing system 60 are not limited to the illustrated numbers.

The information processing apparatus 10 is a computer that executes a program that realizes a method of transmitting and receiving a mail and a method of determining a mail destination. The information processing apparatus 10 has a function as a mail server and a WWW (World Wide Web) server. The user can use the function of logging in to the information processing device 10 through a program such as a browser executed on the terminals 20 and 30 and transmitting and receiving mail. The information processing device 10 accepts a mail transmission request from the terminals 20 and 30, determines whether or not there is a problem with the destination of the mail that accepted the transmission request, and if there is a problem, the requesting terminal 20, 30. Display a message to alert (display an alert).

The information processing device 10 includes a control unit 11 and a storage unit 12. The control unit 11 controls the entire information processing apparatus 10, and is, for example, a processor or the like. The control unit 11 performs information communication with various devices. In addition, the control unit 11 can store and read information in the storage unit 12. The storage unit 12 is a storage device such as a memory or a disk, and stores history information regarding mail operations. The storage unit 12 stores the transmission history information 15 and the operation history information 16.

The transmission history information 15 is information that stores a transmission history for each user who is the sender of the mail. The information processing device 10 stores the information of the transmitted history of the mail for which the transmission request is accepted in the transmission history information 15 together with the information regarding the mail (transmission date/time, source, destination). The destination is stored by distinguishing the type of destination (TO, CC, BCC).

The operation history information 16 is information that records the operation input to the alert target mail by the user after the information processing apparatus 10 presents the alert. The information processing apparatus 10 determines the address of the mail for which the transmission request has been accepted, and when it determines that there is a problem with the address of the mail, presents a message to the effect of attention to the requesting terminals 20, 30. After observing the alert presented by the information processing device 10, the user performs an operation input to the terminals 20 and 30 to transmit or cancel the transmission of the email targeted by the alert. The information processing apparatus 10 accepts a user's operation input via the terminals 20 and 30, and stores the user's operation input in the operation history information 16 together with the information (transmission date/time, transmission source, transmission destination) regarding the alert target mail.

The terminals 20 and 30 are computers used by users. The user accesses the information processing apparatus 10 via the terminals 20 and 30 and uses the function of the program executed by the information processing apparatus 10. The user logs in to the information processing device 10 using a browser or the like executed on the terminals 20 and 30, uses the function provided for each user, and browses the information presented for each user from the information processing device 10. It is possible to

Here, a mail destination determination method in the information processing system 60 will be described. It is assumed that the user A uses the terminal 20 to send a mail. Further, it is assumed that the user B receives the mail using the terminal 30. Further, each user is assumed to be able to log in to the information processing device 10 in advance via the terminals 20 and 30 and use the function of the program executed by the information processing device 10.

(1) The terminal 20 accepts a mail transmission request from the user A and transmits the mail transmission request to the information processing device 10.
(2) The control unit 11 of the information processing device 10 receives a mail transmission request from the terminal 20. The control unit 11 reads the transmission history information 15 of the user A, who is the sender of the mail, from the storage unit 12, and determines whether there is a problem with the destination of the mail based on the transmission history information 15 of the user A.

Here, there are a plurality of methods for the control unit 11 to determine the destination of the mail. Below, examples of a method of determining the destination of the mail will be described as (Example 1) to (Example 3).
(Example 1) This is a method in which the control unit 11 applies the association analysis to the transmission history information 15 to obtain the support, and determines whether or not there is a problem with the destination of the mail for which the transmission request is received. The control unit 11 calculates the support level based on the number of cases in which the transmission history information 15 includes the same destination as the destination of the email for which the transmission request has been accepted and the total number of email transmissions of the user who is the email sender. The control unit 11 determines that there is a problem with the destination of the email for which the transmission request is accepted when the support value of the destination of the email for which the transmission request is accepted is lower than the reference value. The reference value is a reference value for determining whether the support is high or low. The reference value may be a value set in advance by the system administrator, or may be a predetermined value based on the transmission history information 15 (for example, the degree of support for 1% of the number of emails stored in the transmission history information 15). Value) may be calculated and obtained.

(Example 2) The control unit 11 divides the transmission history information 15 into at least two different periods, obtains the evaluation value for the destination of the email that receives the transmission request for each period, and compares the evaluation values for each period to obtain the email. This is a method of determining whether or not there is a problem with the destination. The evaluation value may be a value for evaluating the destination of the mail, and may be a support level or another value. Of the two different periods, a predetermined period close to the date and time when the email transmission request is received is the first period, and a period longer than the first period is the second period. For example, the control unit 11 sets a period of the most recent two months from the date of receiving the email transmission request as the first period, and sets a period of the past one year from the date of receiving the email transmission request as the second period. The control unit 11 obtains a first evaluation value, which is a value for evaluating the destination of the mail, based on the information stored in the transmission history information 15 in the first period. The control unit 11 obtains the second evaluation value, which is a value for evaluating the destination of the mail, based on the information stored in the transmission history information 15 in the second period. When the first evaluation value is higher than the reference value, the control unit 11 determines that there is no problem with the mail destination. When the first evaluation value is lower than the reference value and the second evaluation value is higher than the reference value, the control unit 11 determines that there is a problem with the destination of the mail, and the destination of the mail after the predetermined period elapses. Present a message to the terminal to alert you that it is a transmission. When both the first evaluation value and the second evaluation value are lower than the reference value, the control unit 11 determines that there is a problem with the mail destination, and calls attention to confirm whether the mail destination is correct. A message to that effect is presented to the terminal.

(Example 3) This is a method in which the control unit 11 determines, based on the operation history information 16, whether or not there is a problem with the destination of the mail for which the transmission request is received. When the operation history information 16 includes the same destination as the mail destination, the control unit 11 determines whether or not there is a problem with the mail destination based on the content of the user operation registered in the same entry. judge.

For example, a case will be described in which the sender of the mail that has received the transmission request is “A” and the recipient (TO) is “B, Z”. The control unit 11 extracts an entry in which the transmission date and time of the operation history information 16 in which the same destination as the received email is registered is “9/1 15:00”. The control unit 11 determines that there is a problem with the destination of the received mail because the item indicating the operation input of the user registered in the extracted entry is “stop transmission”.

In addition, when the item indicating the operation input of the user registered in the extracted entry is “send”, the control unit 11 determines that there is no problem in the destination of the received mail.
(3) The control unit 11 determines the destination of the email that has received the transmission request, and if it determines that there is a problem with the destination of the email, presents a message to the terminal 20 to alert (display an alert). ) Do. The user A visually confirms the alert via the terminal 20 and confirms the email targeted by the alert.

When the control unit 11 determines that there is no problem with the mail destination, the control unit 11 sends the mail to the mail destination (for example, user B).
(4) The terminal 20 accepts an operation input (transmission or transmission stop) for the email targeted by the alert from the user A, and transmits it to the control unit 11. The control unit 11 stores the operation input received from the terminal 20 in the operation history information 16. When the control unit 11 receives an operation input instructing “transmission” from the user A, the control unit 11 transmits the mail to the destination. When the control unit 11 receives an operation input instructing “stop transmission” from the user A, the control unit 11 stops sending the mail.

In this way, the information processing device 10 determines the destination of the mail that has received the transmission request, and when it determines that there is a problem with the destination, sends a message to the attention to the terminals 20 and 30. As a result, the information processing apparatus 10 can present a message to the user when there is a problem with the address, and thus improves the convenience for the user as compared with the case where the message is not displayed without simply sending the mail. it can. Further, since the information processing device 10 can determine the destination of the mail using the transmission history information 15 and the operation history information 16, the information processing device 10 more appropriately determines whether or not there is a problem with the destination of the mail, and informs the user. You can call attention to them.

In this way, the information processing apparatus 10 sends a mail after a long time, if it is a destination that has not been sent in the past (or if the number of transmissions is small), or if the combination of destinations is different from the sent history. If there is a high possibility that an erroneous transmission is made, such as when the affiliation of the other party has been changed, it is determined that the mail address is problematic. When the information processing apparatus 10 determines that there is a problem with the destination, it presents a message to the terminals 20 and 30 to alert the user, thereby preventing erroneous transmission of the mail.

In this way, the information processing system 60 can more appropriately execute the alerting when the erroneous transmission of the mail is prevented.
[Second Embodiment]
Next, as the second embodiment, an information processing system in which the information processing device 10 is applied to a server will be described with reference to FIG. FIG. 2 is a diagram illustrating an example of the information processing system according to the second embodiment.

The server 100 is a computer that executes a program that realizes a mail system. The server 100 manages emails sent and received by the terminals 200, 300 and 310. The server 100 accepts the mail transmission request from the terminals 200, 300, 310, and when it determines that there is a problem in the mail destination, presents an alert for preventing the wrong transmission of the mail to the terminals 200, 300, 310. The server 100 also has a function as a WWW server, and can present information to the terminals 200, 300, 310 as Web pages.

The terminal 200 is a computer used by the user A. The terminal 300 is a computer used by the user B. The terminal 310 is a computer used by the user C. The terminals 200, 300 and 310 may be desktop computers, notebook computers, tablet computers, or portable computers. It is assumed that the terminals 200, 300, and 310 can communicate with the server 100 and can execute a program such as a browser and use the function of the program provided by the server 100.

In the following description, the user A may be described as a mail sender and the user B or the user C may be described as a mail recipient. In addition, unless a user A, a user B, or a user C is specified, it is described as a user. Further, it is referred to as the terminal 200 unless any of the terminals 200, 300 and 310 is specified.

Next, the hardware configuration of the server according to the second embodiment will be described with reference to FIG. FIG. 3 is a diagram illustrating an example of the hardware configuration of the server according to the second embodiment.
The server 100 includes a processor 111, a RAM (Random Access Memory) 112, an HDD (Hard Disk Drive) 113, an image signal processing unit 114, an input signal processing unit 115, a medium reader 116, and a communication interface 117. The server 100 is entirely controlled by a processor 111. The RAM 112 and a plurality of peripheral devices are connected to the processor 111 via a bus 118. The processor 111 may be a multiprocessor. The processor 111 is, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), or a PLD (Programmable Logic Device). Further, the processor 111 may be a combination of two or more elements of CPU, MPU, DSP, ASIC, PLD.

The RAM 112 is used as a main storage device of the server 100. The RAM 112 temporarily stores at least part of an OS (Operating System) program and application programs to be executed by the processor 111. Further, the RAM 112 stores various data necessary for the processing by the processor 111.

The peripheral devices connected to the bus 118 include the HDD 113, the image signal processing unit 114, the input signal processing unit 115, the medium reader 116, and the communication interface 117.
The HDD 113 magnetically writes and reads data to and from the built-in disk. The HDD 113 is used as an auxiliary storage device of the server 100. The HDD 113 stores an OS program, application programs, and various data. The HDD 113 is not limited to the SSD (Solid State Drive). A semiconductor memory device such as a flash memory may be used as the auxiliary memory device.

The image signal processing unit 114 outputs an image to the display 114a connected to the server 100 according to the instruction from the processor 111. As the display 114a, a CRT (Cathode Ray Tube) display, a liquid crystal display (LCD: Liquid Crystal Display), a plasma display, an organic EL (OEL: Organic Electro-Luminescence) display, or any other type of display can be used.

The input signal processing unit 115 acquires an input signal from the input device 115a connected to the server 100 and outputs the input signal to the processor 111. Any type of input device such as a mouse, a touch panel, a touch pad, a trackball, a keyboard, a remote controller, or a button switch can be used as the input device 115a.

The medium reader 116 is a reading device that reads programs and data recorded on the recording medium 119. As the recording medium 119, for example, a magnetic disk, an optical disk, a magneto-optical disk (MO: Magneto-Optical disk), a semiconductor memory, or the like can be used. The magnetic disk includes a flexible disk (FD: Flexible Disk) and an HDD. The optical disc includes a CD (Compact Disc) and a DVD (Digital Versatile Disc).

The medium reader 116, for example, copies the program or data read from the recording medium 119 to another recording medium such as the RAM 112 or the HDD 113. The read program is executed by the processor 111, for example. The recording medium 119 may be a portable recording medium and may be used for distributing programs and data. The recording medium 119 and the HDD 113 may be referred to as a computer-readable recording medium.

The communication interface 117 is connected to the network 400. The communication interface 117 transmits/receives data to/from another computer, a storage device, or a communication device.

With the above hardware configuration, the processing function of the server 100 of the second embodiment can be realized. The information processing apparatus 10 and the terminals 20 and 30 of the first embodiment can be realized by the hardware configuration of the server 100 shown in FIG. Further, the terminals 200, 300, 310 of the second embodiment can also be realized by the hardware configuration of the server 100 shown in FIG.

Note that the above configuration is an example, and the combination of components can be appropriately determined. For example, when the terminal 200 is a portable computer, the display 114a and the input device 115a may be replaced with a liquid crystal screen and a touch panel integrated with the main body and a wireless communication function.

The server 100 realizes the processing functions of the second embodiment by executing a program recorded in a computer-readable recording medium, for example. The program describing the processing content to be executed by the server 100 can be recorded in various recording media. For example, the program executed by the server 100 can be stored in the HDD 113. The processor 111 loads at least a part of the programs in the HDD 113 into the RAM 112 and executes the programs. Further, the program to be executed by the server 100 may be recorded in a portable recording medium such as an optical disc, a memory device, a memory card. The program stored in the portable recording medium becomes executable after being installed in the HDD 113 under the control of the processor 111, for example. Further, the processor 111 can directly read out and execute the program from the portable recording medium.

Next, an example of the transmission log information stored in the server 100 according to the second embodiment will be described with reference to FIG. FIG. 4 is a diagram illustrating an example of transmission log information according to the second embodiment.
The transmission log information 600 is information for managing the history (log) of emails sent by the user. The transmission log information 600 is information managed for each user. The server 100 receives a mail transmission request from the user via the terminal 200, performs a mail transmission process, and stores information of the mail subjected to the transmission process in the transmission log information 600. The server 100 stores the transmission log information 600 in a storage unit such as the HDD 113 or the RAM 112.

The transmission log information 600 includes items of transmission date and time, transmission source address, transmission destination address (TO), transmission destination address (CC), transmission destination address (BCC), and status.
In the item of transmission date and time, the transmission date and time (year/month/day/hour) of the mail is registered. The email address of the user of the email sender is registered in the item of the sender address. The mail address of the mail destination is registered in the destination address (TO) item. If there is no destination address, "-" is registered.

An email address of Carbon Copy is registered in the item of destination address (CC). When the mail sender simultaneously reports the mail to users other than the user designated as the mail destination (TO), the mail sender describes the mail address of the other user in the carbon copy (CC) destination.

Blind Carbon Copy mail addresses are registered in the destination address (BCC) field. The mail sender is to notify the mail to other users at the same time other than the user designated as the mail destination (TO), and when hiding the mail addresses of other users, blind carbon copy (BCC) is used. ) Write the email addresses of other users to the destination of.

In the status item, the mail transmission status is registered. For example, when the transmission of the email is completed, the server 100 registers “transmission completed” in the status. Further, the server 100 registers an error message in the status when the mail cannot be transmitted.

Here, the entries registered in the items included in the transmission log information 600 will be described. In the transmission log information 600, the transmission date and time is “2018/9/6 6:00”, the transmission source address is “A@abc.com”, the transmission destination address (TO) is “B@bbb.co.jp”, Information in which the destination address (CC) is "-", the destination address (BCC) is "-", and the status is "transmission completed" is registered.

This means that an e-mail is sent when the sending date and time is "September 6, 2018, 6:00", the sending user's mail address is "A@abc.com", and the sending user's mail address (TO) is " B@bbb.co.jp”. Further, the destination address (CC) and the destination address (BCC) do not exist, indicating that the status (status) of sending the mail is “transmission completed”.

The items included in the transmission log information 600 are merely examples, and the combination of items can be appropriately determined. For example, unnecessary items may be deleted from the above items, or other items may be added.

Next, an example of the operation log information stored in the server 100 according to the second embodiment will be described with reference to FIG. FIG. 5 is a diagram showing an example of the operation log information according to the second embodiment.
The operation log information 610 is information that manages the history (log) of the user's operation after an alert for preventing erroneous transmission of mail is displayed on the terminal 200 used by the user. The operation log information 610 is information managed for each user.

The server 100 accepts the mail transmission request from the terminal 200, and when it determines that there is a problem in the mail destination, presents an alert to the terminal 200 for preventing erroneous mail transmission. The terminal 200 receives an operation input from the user who visually confirms the alert, and transmits it to the server 100. The server 100 stores the operation input of the user transmitted by the terminal 200 in the operation log information 610. The server 100 stores the operation log information 610 in a storage unit such as the HDD 113 or the RAM 112.

The operation log information 610 includes items of operation date/time, source address, destination address (TO), destination address (CC), destination address (BCC), alert type, and user operation. The items of the source address, the destination address (TO), the destination address (CC), and the destination address (BCC) are the same as those in the transmission log information 600, and thus the description thereof will be omitted.

In the operation date/time item, the date/time (year/month/day/hour/minute) at which the user who has viewed the alert performed an operation to determine whether or not to send an email is registered.
The alert type is registered in the alert type item. There are three types of alerts, namely, association, transmission log, and operation log. The “association” of the alert type is the alert type when the alert is output as a result of the support level confirmation process for the mail destination. The support confirmation process will be described later with reference to FIG. The "send log" of the alert type is an alert type when the alert is output as a result of performing the send log analysis process on the mail destination. The transmission log analysis process will be described later with reference to FIG. The “operation log” of the alert type is an alert type when an alert is output based on the operation log information 610 for a mail destination. Generation of an alert based on the operation log information 610 will be described later with reference to FIG.

In the item of user operation, the operation of whether or not the user who has viewed the alert on the terminal 200 has to send the mail determined to have a problem by the server 100 is registered. For example, when an alert indicating that the email has a problem with the email destination is displayed on the terminal 200 and then the user selects "send" for the email, "send" is recorded in the user operation. Further, after the alert indicating that the mail has a problem in the destination of the mail is displayed on the terminal 200, if the user selects “stop sending” for the mail, “stop sending” is recorded in the user operation.

Conventionally, the server 100 could not record an email that was not sent because it was stopped, because it was not sent or received. However, by using the operation log information 610, the server 100 can record the user operation after the alert is displayed.

Here, the entries registered in the items included in the operation log information 610 will be described. In the operation log information 610, the operation date and time is “2018/9/7 12:00”, the source address is “A@abc.com”, and the destination address (TO) is “B@bbb.co.jp D@”. defg.com", the destination address (CC) is "-", the destination address (BCC) is "-", the alert type is "association", and the user operation is "send".

This is because the date and time when the user operated the alert after visually checking it was “September 7, 2018, 12:00”, the sender user's email address was “A@abc.com”, and the recipient user's email address. (TO) indicates “B@bbb.co.jp” and “D@defg.com”. Further, the destination address (CC) and the destination address (BCC) do not exist, the type of the email alert is “association”, and the operation performed by the user is “send email”.

The items included in the operation log information 610 are merely examples, and the combination of items can be appropriately determined. For example, unnecessary items may be deleted from the above items, or other items may be added.

Next, an example of the destination check setting information stored in the server 100 according to the second embodiment will be described with reference to FIG. FIG. 6 is a diagram illustrating an example of the destination check setting information according to the second embodiment.

The destination check setting information 700 is information that sets a method for checking the destination of a mail in the server 100. The system administrator of the information processing system 500 can set what kind of destination check process is to be executed in the server 100 by registering the execution flag of the destination check setting information 700. The server 100 stores the destination check setting information 700 in a storage unit such as the HDD 113 or the RAM 112.

The destination check setting information 700 includes items of destination check process name and execution flag. In the address check process name item, the name of the check process for checking the mail destination is registered. As an example of the check process, there is an indication level confirmation process (association analysis) that is a process of confirming the support obtained by using the association analysis and a transmission log analysis process. In the item of the execution flag, "1" is registered in the process to be executed and "0" is registered in the process not to be executed. As the destination check process, either one or both of the support level confirmation process and the transmission log analysis process is executed.

Here, the setting information of the destination check setting information 700 will be described. In the destination check setting information 700, "1" is registered in the execution flag of the "support level confirmation process" of the destination check process name, and "1" is registered in the execution flag of the "transmission log analysis process" of the destination check process name.

This indicates that both the "support level confirmation process" and the "transmission log analysis process" are executed (execution flag "1") as the destination check process executed by the server 100.
Next, an example of the support table stored in the server 100 according to the second embodiment will be described with reference to FIG. 7. FIG. 7 is a diagram illustrating an example of a support level table according to the second embodiment.

The support level table 710 is information in which the support level obtained by the server 100 using association analysis is recorded. The process in which the server 100 calculates the support will be described later with reference to FIG. The server 100 stores the support table 710 in a storage unit such as the HDD 113 or the RAM 112.

The support table 710 includes items of a source address, a destination, and a support. The email address of the user of the email sender is registered in the item of the sender address. In the destination item, the mail address of the mail destination is registered for each type (TO, CC, BCC) of the destination. The support level calculated by the server 100 is registered in the support level item. The server 100 calculates the support for each combination of the source address and the destination, and registers the support in the support table 710.

Here, the registration information of the support table 710 will be described. For example, in the support table 710, the source address is “A@abc.com”, the destination address (TO) is “B@bbb.co.jp”, and the destination address (CC) is “ "-", "-" is registered in the destination address (BCC) of the destination, and "0.82" is registered in the support level.

This is the support calculated by extracting from the transmission log information 600 the history that the server 100 has transmitted from the transmission source address “A@abc.com” to the transmission destination address (TO) “B@bbb.co.jp”. Is "0.82". It should be noted that the server 100 calculates the support for each type (TO, CC, BCC) of the transmission destination even if the transmission source address and the transmission destination address are the same address, and registers the support degree in the support degree table 710.

Next, a sequence in the information processing system 500 according to the second embodiment will be described with reference to FIG. FIG. 8 is a diagram showing an example of a sequence of the information processing system of the second embodiment.

A sequence of processing executed by the terminal 200 and the server 100 in the information processing system 500 will be described. The processing executed by the terminal 200 is executed by the control unit (processor) included in the terminal 200. The processing executed by the server 100 is executed by the control unit (processor 111) included in the server 100.

The terminal 200 receives an input of a login processing request from the user via the function of the browser included in the terminal 200, and transmits the login processing request to the server 100. The control unit of the server 100 receives the login processing request from the terminal 200 and executes the processing. After the login permission notification from the server 100, the terminal 200 provides the user with the function of the mail processing program executed by the server 100 via the browser function.

[Step S<b>11] The terminal 200 accepts the information input of the login processing request from the user and transmits it to the server 100. Specifically, the terminal 200 accepts the input of the user ID and the password from the user, and transmits the input user ID and the password together with the login processing request to the server 100.

[Step S12] The server 100 receives the login processing request from the terminal 200, authenticates the user ID and the password, and executes the login processing. It is assumed that the server 100 gives access permission for the function of the mail processing program provided by the server 100 to the user who has logged in from the terminal 200.

[Step S13] The terminal 200 accepts a mail creation process from the user and sends a request to send the created mail to the server 100.
[Step S14] The server 100 executes the destination check process for the mail for which the transmission request is received from the terminal 200. The destination check process is a process in which the server 100 checks the destination of the mail in order to prevent erroneous transmission of the mail. The destination check process will be described later with reference to FIG.

[Step S15] The server 100 determines whether there is a problem with the destination of the mail based on the result of the destination check process. The server 100 proceeds to step S16 if there is a problem with the mail destination, and proceeds to step S17 if there is no problem with the mail destination.

[Step S16] The server 100 notifies the terminal 200 of an alert notifying that there is a problem with the mail destination. The server 100 generates an alert in the destination check process.

[Step S17] If there is no problem with the destination of the mail, the server 100 sends the mail to the destination.
[Step S18] The terminal 200 receives an alert from the server 100 and displays the received alert on the display. In addition, the terminal 200 displays an alert and also displays a screen that prompts the user to determine whether or not to send a mail for which there is a problem with the destination, and prompts the user to select whether to send or not.

For example, the terminal 200 displays, "This email has been determined to have a problem with the recipient. Do you want to send it? Click the "Yes" button to send, or the "No" button to cancel sending. please do it. Is displayed, and the user is prompted to select whether transmission is necessary or not by button input.

[Step S19] The terminal 200 receives a user operation input (mail transmission/mail transmission stop) after the alert is displayed, and transmits the user operation input to the server 100.
[Step S20] The server 100 receives a user operation input from the terminal 200 and stores it in the operation log information 610. Specifically, the server 100 stores the operation date and time, the address described in the mail, and the like in the operation log information 610 as well as the user operation input (transmission/transmission cancellation).

[Step S21] The server 100 executes mail processing according to a user operation input. For example, the server 100 sends a mail when the user operation input is “send”. If the user operation input is “cancel transmission”, the server 100 cancels the transmission of the email and discards the email.

In this way, the server 100 stores the operation input of the user after the alert is generated in the operation log information 610, and uses the operation log information 610 in the destination check process of the next mail to determine the feedback of the user operation input. Is possible.

Next, the destination check process in the server 100 of the second embodiment will be described with reference to FIG. FIG. 9 is a diagram illustrating an example of a flowchart of the destination check processing according to the second embodiment.

The destination check process is a process in which the server 100 checks the destination of the mail in order to prevent erroneous transmission of the mail. The destination check process is a process executed by the control unit (processor 111) of the server 100 in step S14 of the sequence of FIG.

[Step S31] The server 100 reads the destination check setting information 700, and determines the process name for which the execution flag is “1”. If the process in which the execution flag is “1” is only the support degree confirmation process, the server 100 proceeds to step S32. If the process having the execution flag of “1” is only the transmission log analysis process, the server 100 proceeds to step S33. If the process having the execution flag of “1” is both the support level confirmation process and the transmission log analysis process, the server 100 proceeds to step S34.

[Step S32] The server 100 executes a support level confirmation process for the mail for which the transmission request is received from the terminal 200. The support level confirmation process is a process of determining the possibility of erroneous transmission of a mail address based on the support level obtained by the server 100 using association analysis. The support confirmation process will be described later with reference to FIG.

[Step S33] The server 100 executes a transmission log analysis process for the mail for which the transmission request is received from the terminal 200. The transmission log analysis process is a process in which the server 100 determines the possibility of erroneous transmission of a mail destination based on the transmission log information 600. The transmission log analysis process will be described later with reference to FIG.

[Step S34] The server 100 executes a support level confirmation process for the mail for which the transmission request is received from the terminal 200. The processing of this step is the same as that of step S32, and therefore its explanation is omitted.

[Step S35] The server 100 executes a transmission log analysis process for the mail for which the transmission request is received from the terminal 200. The processing of this step is the same as that of step S33, and therefore its description is omitted.

[Step S36] The server 100 reads the operation log information 610, and determines whether or not the same destination as the destination described in the email for which the transmission request is received exists in the operation log information 610. The server 100 proceeds to step S37 if the same destination exists in the operation log information 610, and ends the process if it does not exist.

[Step S37] The server 100 determines whether or not “Cancel transmission” is registered in the item of user operation for the entry of the operation log information 610 that is the same destination as the destination described in the email that received the transmission request. judge. The server 100 proceeds to step S38 if the item of the user operation is “transmission stopped”, and proceeds to step S40 otherwise.

[Step S38] Based on the operation log information 610, the server 100 generates a result indicating that “there is a problem” with respect to the destination of the mail for which the transmission request is received.
[Step S39] The server 100 generates an alert based on the operation log information 610. The server 100 can create a message based on the operation log information 610 and add it to an alert. For example, the server 100 can add a message "The destination of this mail is the same as the destination whose transmission was stopped at 9:55 on September 10, 2018. Please reconfirm the destination of the mail." The server 100 ends the process after generating the alert.

[Step S40] The server 100 determines whether a predetermined time has elapsed. The predetermined time is, for example, the time until the server 100 updates the mail transmission log information 600 and can execute the destination check process based on the updated transmission log information 600. The predetermined time is a time that the system administrator can set in the server 100. When causing the server 100 to update the transmission log information 600 by batch processing once a day, the system administrator can set the predetermined time to one day (24 hours) according to the timing of batch processing.

If the predetermined time has elapsed, the server 100 proceeds to step S38, and if the predetermined time has not elapsed, proceeds to step S41.
It should be noted that when the user operation is “transmission” (NO in step S37), the server 100 performs the processing of this step (NO in this step) and step S41 in the destination of the mail to be transmitted. Is a process of stopping the notification of the alert to the user for a predetermined time. As a result, the server 100 can suppress the occurrence of unnecessary alerts for the mail in which the destination determined to be sent by the user is described. For example, when a user sends an email to a new destination, an alert is notified at the first time, and it is necessary to select "Send" by the user operation, but the notification of the alert can be suppressed after the second time. ..

[Step S41] Based on the operation log information 610, the server 100 generates a result of “no problem” with respect to the destination of the mail for which the transmission request is received, and ends the process.
Next, the support level confirmation process in the server 100 of the second embodiment will be described with reference to FIG. FIG. 10 is a diagram illustrating an example of a flowchart of the support level confirmation processing according to the second embodiment.

The support level confirmation process is a process of determining the possibility of erroneous transmission of a mail address based on the support level obtained by the server 100 using association analysis. The support level confirmation process is a process executed by the control unit (processor 111) of the server 100 in steps S32 and S34 of the destination check process.

[Step S51] The server 100 reads the transmission source user of the mail for which the transmission request is received and the destination described in the mail.
[Step S52] The server 100 refers to the support table 710 from the storage unit, and acquires the support corresponding to the combination of the mail transmission source and the destination.

[Step S53] The server 100 determines whether the support obtained from the support table 710 is lower than the support reference value. The support reference value is a reference value for determining whether the support is high or low. The support standard value is obtained, for example, by determining the support rate for the reference number as “reference number/total number”, with the reference number being the ratio of the total number of emails in the past year included in the transmission log information 600. This value can be set as the supporting reference value. Specifically, when the total number of emails in the past year is 100, the predetermined ratio is 2%, and the reference number is 2, the value “0.02” obtained by “2÷100”. Can be set as a support reference value. The support reference value may be determined in advance by the system administrator and stored in the storage unit of the server 100.

The server 100 proceeds to step S54 if the support level is lower than the support reference value, and proceeds to step S56 otherwise.
[Step S54] Based on the association analysis, the server 100 generates a result that "there is a problem" with respect to the destination of the mail for which the transmission request is received.

[Step S55] The server 100 generates an alert based on the association analysis. The server 100 can create a message based on the association analysis and attach it to the alert. For example, the server 100 can add a message "This mail address combination is a combination that has not been sent in the past. Please reconfirm the mail address." The server 100 ends the process after generating the alert.

[Step S56] Based on the association analysis, the server 100 generates a result "no problem" for the destination of the mail for which the transmission request is received, and ends the process.
Next, the support degree calculation process in the server 100 of the second embodiment will be described with reference to FIG. FIG. 11 is a diagram illustrating an example of a flowchart of the support degree calculation processing according to the second embodiment.

The support calculation process is a process in which the server 100 calculates the support for each combination of the transmission source and the transmission destination using the transmission log information 600. The control unit (processor 111) of the server 100 executes the support degree calculation processing independently of the support degree confirmation processing. For example, the server 100 executes the support calculation processing as batch processing once a day at night or the like.

[Step S61] The server 100 acquires the transmission log information 600 from the storage unit.
[Step S62] The server 100 calculates the support for each combination of the transmission source and the transmission destination included in the transmission log information 600 based on the transmission log information 600.

For example, the server 100 identifies the target sender whose target is to be calculated from the transmission log information 600 and the target destination whose target is to be calculated as “the number of emails whose target destination is the destination/target” The support level is calculated by obtaining the "number of all sender emails". When the “number of mails whose destination is a destination” is “0”, the support value is “0”.

Here, the target destination will be described. Regarding the destinations described in the email, the number of cases is counted with the destination address (TO), the destination address (CC), and the destination address (BCC) as different destinations. For example, a mail whose destination address (TO) is "B@bbb.co.jp" and a mail whose destination address (CC) is "B@bbb.co.jp" are counted as different mails. To do. Even if the senders are the same email address, if the destination types (TO, CC, BCC) are different, the number of emails is counted as different recipients. Further, when the support is calculated, a mail having only the target destination and a mail including the target destination in one of the plurality of destinations described in the same mail are counted as different.

The server 100 also calculates the support level for the combination of destinations (target destination group). For example, the server 100 identifies a target sender whose target is calculated from the transmission log information 600 and a target destination group whose target is calculated from the transmission log information 600, and determines “the number of emails whose target destination is the destination”. ÷ The support level can be calculated by obtaining the “number of target senders of all emails”. When the “number of mails whose destination group is the destination” is “0”, the support value is “0”. The method of calculating the support is merely an example, and other methods may be used.

Here, the target destination group will be described. A mail whose destination address (TO) is “B@bbb.co.jp” and a destination address (BCC) is “D@defg.com”, and a destination address (TO) is “B@bbb.co.jp”. jp” and “D@defg.com” are counted as the destinations different from the mails. Even if the same mail address is included, if “TO”, “CC”, and “BCC” are different between the target destination group and the entry of the transmission log information 600, the number of mails is counted as different destinations.

Further, a mail whose destination address (TO) is “B@bbb.co.jp”, “D@defg.com” and “Z@zzzz.com” and a destination address (TO) is “B@bbb. .Co.jp" and "D@defg.com" are counted as the destinations different from the mails. Even if the same e-mail address is included in a part of the target destination group, if all the e-mail addresses in the target destination group are not the same as the entries of the transmission log information 600, the number of mails is counted as a different destination. To do.

Also, when calculating the support level, mails with only the target destination group and mails in which some of the multiple destinations described in the same mail are the same as some of the target destination group are counted as different. ..

For example, the first example will be described. In the description here, the description of the mail address is simplified and described with one alphabet. It is assumed that the first mail having the destination address (TO) of “B, C, D” is recorded in the transmission log information 600. In this case, the support value for the second mail having the destination address (TO) of the target destination group of “C, D, E” is “0”. In the first example, the part “C, D” of the target destination group of the second mail is the same as the part of the first mail recorded in the transmission log information 600, but is not completely the same. Support is calculated as different.

A second example will be described. A third mail having a destination address (TO) of “E, F, G” and a fourth mail having a destination address (TO) of “E, F, H” are recorded in the transmission log information 600. It is assumed that In this case, the value of the support level is “0” for the fifth mail whose destination address (TO) of the target destination group is “G, H”. In the second example, a part "G" of the destination of the third mail and a part "H" of the destination of the fourth mail are the same as a part of the target destination group of the fifth mail, respectively. Since the combinations of the destinations are not completely the same, the support is calculated by counting them as different.

Also, a third example will be described. A sixth mail having a destination address (TO) of “J, K, L” and a seventh mail having a destination address (TO) of “J, K, M” are recorded in the transmission log information 600. It is assumed that In this case, the value of the support is “0” for the eighth mail whose destination address (TO) of the target destination group is “J, K, L, M”. In the third example, the destination of the eighth mail includes all of the destinations of the sixth mail and the seventh mail, but since the combinations of the respective destinations are not completely the same, they are counted as different and the support is counted. calculate.

Further, a fourth example will be described. It is assumed that the ninth mail having the destination address (TO) of “A, B, C” is recorded in the transmission log information 600. In this case, the degree of support for the 10th mail whose destination address group (TO) is “A, B”, the 11th mail which is “B, C”, and the 12th mail which is “A, C” Also, the number of 9th mails is counted. This is because the destinations of the 10th to 12th mails are all included in the destinations of the 9th mail. In addition, the support for the 13th mail having the destination address (TO) of “A”, the 14th mail having “B”, and the 15th mail having “C” has the number of the 9th mail as well. Is counted. This is because the destinations of the 13th to 15th mails are all included in the destinations of the 9th mail.

[Step S63] The server 100 stores the support calculated in step S62 in the support table 710. The server 100 can determine whether or not there is a problem with the mail destination by using the support level table 710 in which the support level is recorded in the support level confirmation process.

In this way, the server 100 calculates the support level using the association analysis and determines whether or not there is a problem with the mail destination based on the support level. With this, the server 100 can determine whether or not the destinations to which the individual emails have been transmitted in the past are appropriate destinations for the destinations that combine the respective destinations as different destinations.

For example, in the information processing system 500, the case where the user A sends a mail to the user B and the user C will be described. It is assumed that the user A has sent the mail individually to the user B and the user C, but has never described the user B and the user C in the same mail destination. In such a case, the possibility of erroneous transmission could not be determined only by the presence/absence of past transmission history. However, the server 100 performs the above-described support degree calculation processing and support degree confirmation processing, and thereby the combination of destinations is obtained. Based on this, it is possible to determine that there is a possibility of erroneous transmission (there is a problem with the destination). More specifically, since the user B and the user C belong to different companies, these processes are performed in the determination when the user A is prohibited from describing the destinations of the user B and the user C in the same mail. Is effective.

Next, the transmission log analysis process in the server 100 of the second embodiment will be described with reference to FIG. FIG. 12 is a diagram illustrating an example of a flowchart of the transmission log analysis process according to the second embodiment.

The transmission log analysis process is a process in which the server 100 determines the possibility of erroneous transmission of a mail destination based on the transmission log information 600. Unlike the association analysis, the transmission log analysis process divides the period of the transmission log information 600 and determines whether there is a problem with the mail transmission destination. The transmission log analysis process is a process executed by the control unit (processor 111) of the server 100 in steps S33 and S35 of the destination check process.

[Step S71] The server 100 acquires the transmission log information 600 of the transmission source user of the email that has received the transmission request.
[Step S72] The server 100 reads the destination described in the email that received the transmission request.

[Step S73] The server 100 calculates the first intimacy degree based on the transmission log information 600 from the most recent first period (for example, three months). The degree of intimacy may be an evaluation value used for evaluation of a mail destination, and may be replaced with the support level or another value. The latest may be the date and time when the server 100 receives the mail transmission request, the beginning of the month and day when the server 100 receives the mail transmission request, or the evaluation of other mail destinations. You may decide the day to do as the starting date.

[Step S74] The server 100 calculates the second intimacy degree based on the transmission log information 600 from the most recent second period (for example, 12 months).
[Step S75] The server 100 determines whether or not the first intimacy degree is higher than the intimacy degree reference value. The intimacy degree reference value is a value that serves as a reference for determining whether the intimacy degree (first intimacy degree, second intimacy degree) is high or low. The intimacy reference value may be any value that can be used for determining whether the intimacy degree is high or low, and may be replaced with the support reference value or another value.

The server 100 proceeds to step S76 if the first intimacy degree is higher than the intimacy degree reference value, and proceeds to step S77 otherwise.
[Step S76] Based on the transmission log analysis, the server 100 generates a result "no problem" for the destination of the mail for which the transmission request is received, and ends the processing.

[Step S77] The server 100 determines whether or not the second intimacy degree is higher than the intimacy degree reference value. The server 100 proceeds to step S78 if the second intimacy degree is higher than the intimacy degree reference value, and proceeds to step S80 otherwise.

[Step S78] The server 100 generates a result of “problem” for the destination of the mail for which the transmission request is received, based on the transmission log analysis.
[Step S79] The server 100 generates an alert based on the transmission log analysis. The server 100 can create a message based on the transmission log analysis and attach it to an alert. For example, the server 100 adds a message such as "The destination of this email is a destination that I used to send a lot in the past, but I haven't sent it so much recently." it can. Note that the message added by the server 100 is not limited to this, and may be any message as long as it is a message that calls attention to the confirmation of the mail destination after the elapse of a predetermined period. The server 100 ends the process after generating the alert.

[Step S80] Based on the transmission log analysis, the server 100 generates a result indicating that “there is a problem” with respect to the destination of the mail for which the transmission request is received.
[Step S81] The server 100 generates an alert based on the transmission log analysis. The server 100 can create a message based on the transmission log analysis and attach it to an alert. For example, the server 100 can add a message "This mail is a destination that has not been sent much before and now. Please reconfirm the destination." Note that the message given by the server 100 is not limited to this, and may be any message that calls attention to the confirmation as to whether the destination is correct or not. The server 100 ends the process after generating the alert.

Note that steps S73 and S74 in the transmission log analysis process may be executed in real time, or may be executed as independent processes at different timings. For example, the server 100 executes the processing of steps S73 and S74 as a batch processing once a day at night, and stores the first intimacy degree and the second intimacy degree in the intimacy degree table. The closeness table is not shown. The server 100 refers to the first intimacy degree and the second intimacy degree recorded in the intimacy degree table in the transmission log analysis process, so that the server 100 performs the first intimacy degree and the second intimacy degree each time the transmission log analysis process is executed. It is possible to avoid the load associated with the calculation of

As described above, the server 100 can provide the user with the reason why the mail destination should be noted by providing the alert with the message according to the analysis result. As a result, the user can confirm the display of the alert for the mail and the reason why the alert has occurred, so that the convenience is improved.

In addition, the server 100 provides an alert with a message to that effect, even if the mail has been sent to the past in the past, if the mail has not been sent for a certain period or more from the latest. As a result, the user can visually check the message attached to the alert and confirm the destination, the contents of the mail, etc. with respect to the person to whom the mail is transmitted after a long time.

Further, the server 100 records the operation input of the user after confirming the alert in the operation log information 610, and uses the operation log information 610 for the determination of the destination, which is more appropriate than the determination using only the email transmission record. It is possible to determine the destination.

In this way, the server 100 sends a mail when it is a destination that has not been sent in the past (or a destination with a small number of transmissions), when the combination of the destinations is different from the sent history, or because the email is sent after a long time. If there is a high possibility of erroneous transmission, such as when the affiliation is likely to be changed, the mail destination is determined to be problematic. If the server 100 determines that there is a problem with the destination, it can prevent the erroneous transmission of the mail by presenting a message to the terminal 200 to call attention.

In this way, the information processing system 500 can more appropriately execute the alerting when the erroneous transmission of the mail is prevented.
The above processing functions can be realized by a computer. In that case, a program describing the processing contents of the functions that the information processing device 10 and the server 100 should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing content can be recorded in a computer-readable recording medium. Computer-readable recording media include magnetic storage devices, optical disks, magneto-optical recording media, semiconductor memories, and the like. The magnetic storage device includes a hard disk device (HDD), a flexible disk (FD), a magnetic tape, and the like. The optical disc includes a DVD, a DVD-RAM, a CD-ROM (Read Only Memory)/RW (ReWritable), and the like. The magneto-optical recording medium includes MO and the like.

In order to put the program into the market, for example, a portable recording medium such as a DVD or a CD-ROM in which the program is recorded is sold. It is also possible to store the program in the storage device of the server computer and transfer the program from the server computer to another computer via the network.

The computer that executes the program stores, for example, the program recorded in the portable recording medium or the program transferred from the server computer in its own storage device. The computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute the processing according to the program. Further, the computer can also sequentially execute processing according to the received program each time the program is transferred from the server computer connected via the network.

Further, at least a part of the above processing functions can be realized by an electronic circuit such as DSP, ASIC, PLD.
